The Dynect Platform for Managed DNS
• Managed Rock-Solid DNS• Global IP Anycast network• Active Failover: (disaster
recovery)• Load Balancing: (weighted,
round robin)• Global Routing: (regional
rulesets, real-time)• CDN Control: (costs, testing,
diversity)
This is not a Sales Pitch…Full- Disclosure & Transparency:

Dynect Traffic Management (DTM) – Take
Control
• Managed Global Server Load Balancing (GSLB)
• DNS based, as a service– No hardware– No CAPEX
• Distribute load to datacenters or availability zones in cloud environments
• DTM works in conjunction with existing local load balancers and health monitoring systems

Monitoring and Failover
• DTM can perform health checks against content servers and load balancers to see if traffic should be sent to that node
• Monitoring intervals – 1 minute
• Checks are performed from multiple datacenters to reduce false-positives
• HTTP and HTTP (with response inspection), SMTP, and ICMP checks available
Overcoming Browser
Limitations
• Recursive DNS servers, OSes, and browsers cache data: use extremely low TTLs and ensure fast delivery with anycast
• High performance managed DNS (Dynect Platform) easily handles low TTLs
Load Balancing Options
• Externally measured availability
• Externally measured latency– Real Time Traffic
Management
• Externally exposed internal metrics– Database load
• Internal decisions– Internal monitoring, internal
logic, Dynect API calls
Best Practice for Availability
& Performance
• Multiple geographic regions
• Each with a local load balancer– Enables rapid local failover
for isolated, local incidents • Server crash, disk failure
• Global Server Load Balancing via Dynect Traffic Management– Manage traffic to
geographic regions– Enables rapid global
failover for systemic incidents
• Upstream transit, power
